Abstract
The utility model discloses a double-layer safety protection well lid for preventing reverse opening, and particularly relates to a double-layer safety protection well lid capable of preventing gas or liquid from jacking up the well lid from bottom to top. The well lid comprises a well base, a bearing cover and a protection cover, clamping plates are arranged outwards on the protection cover in the direction of the diameter, sliding grooves same as the clamping plates in number and position are arranged in the side wall between a first supporting face and a second supporting face, the bottom end of each sliding groove is parallel to the second supporting face, lock holes in the horizontal direction are formed, and the height of each lock hole is larger than the thickness of each clamping plate; all the lock holes are arranged in the same direction. Due to the design that the clamping plates of the prevention cover are screwed in the lock holes, gas or liquid in a well is prevented from jacking up the well lid from the interior.
Description
Technical field
Prevent that the double-deck security protection well lid of oppositely opening belongs to a well lid, be specifically related to a kind of have prevent that gas or liquid are by the well lid double-deck security protection well lid of jack-up from top to bottom.
Background technology
Well lid, for greenbelt, sidewalk, motorway, harbour, lane, for hiding the deep-well of road, prevents that people or object from falling.Although well lid is varied, but existing well lid can not stop inner strength by its jack-up.Such as child is naughty, cigarette end or firecrackers are thrown in the well with biogas, gas burst in well, will be by well lid jack-up; The rainwater and for example occurring when heavy rain pours in down a chimney phenomenon, and the water in well can be from inside by well lid jack-up.These bring hidden danger surprisingly all can to our life.
Summary of the invention
In order to address the above problem, the utility model has designed a kind of double-deck security protection well lid of oppositely opening of preventing, this well lid is provided with protective cover below carrying lid, this protective cover have the gas that prevents in well or liquid by protective cover the function from inner jack-up.
The purpose of this utility model is achieved in that
Prevent a double-deck security protection well lid of oppositely opening, comprise well seat, carrying lid and protective cover;
Described carrying lid is circular;
Described protective cover is circular, and diameter is less than the diameter of carrying lid; Protective cover is along diametric(al) to being outside equipped with clamp, and the circle diameter at described place, clamp outer is no more than the diameter of carrying lid; Described clamp has two at least;
Described well seat direction from top to bottom, is disposed with the first supporting surface of annular and the second supporting surface of annular; The end face of well seat is identical with the height of carrying lid to the distance of the first supporting surface; The outside diameter of the first supporting surface is greater than the diameter of carrying lid, and the interior circular diameter of the first supporting surface is less than the diameter of carrying lid; The outside diameter of the second supporting surface is greater than the diameter of protective cover, and the interior circular diameter of the second supporting surface is less than the diameter of protective cover; Between the first supporting surface and the second supporting surface, the sidewall of part, is provided with the chute identical with position with clamp quantity, and chute bottom is parallel with the second supporting surface, is provided with the keyhole of horizontal direction, and the height of keyhole is higher than the thickness of clamp; The direction of all keyholes is identical, is clockwise direction or counter clockwise direction.
Above-mentioned a kind of oppositely double-deck security protection well lid of unlatching that prevents, two clamps are stamped in described protection, and the line of two clamps is positioned on the diameter of protective cover.
Above-mentioned a kind of oppositely double-deck security protection well lid of unlatching that prevents, described protective cover is entity lid or netted lid.
Beneficial effect: due to the utility model Double-layer drain cover, protective cover is along diametric(al) to being outside equipped with clamp, the sidewall of part between the first supporting surface and the second supporting surface, be provided with the chute identical with position with clamp quantity, chute bottom is parallel with the second supporting surface, be provided with the keyhole of horizontal direction, this design is by being screwed in keyhole the clamp of protective cover, prevent gas in well or liquid by protective cover from inner jack-up.
